Panorama of the Medway from Upnor Hill with Chatham Dockyard & Covered Slips in the distance, Rochester beyond and Upnor Castle to the right

This extensive Panorama  shows the key Chatham Covered Slips and H.M. Dockyard centrally in the distance, with St Mary's Church just to the right of the dockyard before the major expansion northward onto St Mary's Island (left) from c. 1860 with the shipbuilding sheds of the 1840s and early 50s which four out of five (the most southerly of two early wooden ones was later lost to fire).
